Just to let you all know,

I received an IMSI (Mouse Systems M4) mouse with mousepad, and that mousepad works with the Ardent's mouse as well.

    It is a mouse systems mouse, model M4Q, and it has the two holes (one red light, one infrared), so I'll need the blue-and-black grid. I've hopefully bought a correct one off eBay, just waiting for it to arrive.

        There's a blue-and-black grid, and an all-black grid, at least with Sun
        mice. Mice that work on one won't work on the other. At least with the
        blue-and-black grid, spacing didn't seem to matter -- I've got three sizes
        of spacing, all three work with the mice that support it.
        Not sure if it applies to your situation, but the Mouse Systems mice with
        two holes, one emitting red light, work with the blue-and-black pads, and
        the newer Sun mice with a single hole works on the black grid. The
        blue-and-black grid looks metallic blue until you take a close look with a
        lighted magnifier.
